Be it known that I, VICTOR E. EDWARDS, a citizen of the United States residing at Worcester, in the county of orcester and Commonwealth of Massachusetts, have. invented a new and useful Improvement in Rolling-Mills, of which the following is a specification, accompanied by drawmgs forming a part of the same, in which Figure 1 represents a plan view of a pair of rolls of a rolling mill, having means for adjusting and driving the same, embodying my present invention, and Fig. 2 is a side elevation of the rolls with their driving and adjusting mechanism shown in Fig. 1, represented partly in section.

Similar reference letters and figures refer to similar parts in the different .views.

The objects of my present invention are to provide means for adjusting a pair of rolls of a'rolling mill with reference to each other and with reference to the cooperating pairs of rolls; to providevmeans for driving said rolls in their adjusted positions, and further to provide an improved method of housing said rolls, and I accomplish these objects by the construction and arrangement of parts as hereinafter described and pointed out in the annexed claims.

Referring to the accompanying drawings,

1, 2, denote the roll housings of a pair of rolls 3, 4, which, in the present instance, are

represented as'vertical rolls. The rolls 3 and 4 are similarly journaled in bearings supported in the housings 1 and 2, and a description of roll 3, which is shown partly in section in Fig. 2, will also apply to'roll 4. The roll 3 is provided with gudgeons 5, 6, the former being journaled in a bearing 7 and the latter being journaled in a bearing 8. The housing 1 is recessed at 9 to provide a space for the roll 3, and the recess 9 is provided at the top and bottom with circular openings 10 and 11. The bearings 7 and 8 are held in the circular openings 10 and 11 in the housing 1. The circular openings 10 and 11 are open on the inner side of the housing 1, which is provided with clamping bolts 12 and 13, by which the housing is clamped upon the bearings 7 and 8. The circular opening 10 is provided with a shoulder 14 which forms asupport for the hearing 7, and the roll 3 and bearing 8 are smaller in diameter than the inside diameter Specification of Letters Patent.

gear 15, which is inmesh with a beveled gear 16 keyed to a driving shaft 17, and held from longitudinal movement in a bearing 18 formed in the framework of the housing 1. The housing 1 is mounted upon a track 19, to-whlch it is adjustably attached by bolts 20. The roll 4 is similarly supported by the housing 2 in bearings which are clamped 1n the housing 2 by clamping bolts 21, 22. The rolls 3 and 4 are held 1n proper relation to each other by means of adjustable connectmg mechanism between the housings 1 and 2, consisting, in the present instance, of a yoke23 which is pivoted on studs 24 carrled by the housing 2, and is provided with an adjusting screw 25 which bears against the housing 1 to resist the spreading of the rolls 3 and 4. The housing 2 is mounted upon a track 19 and is adjustably attached thereto by bolts 26. I V To the lowergudgeon of the roll 4 is attached a pinion 27, which meshes with a pinion 28 carried upon a sleeve 29, and held from longitudinal movement in a bearing 30 in the housing 2. The sleeve 29 is extended at 31 and carries upon its opposite end a pinion 32, which is in mesh with along toothed pinion 33 upon a driving spindle 34. The shaft 17 is likewise provided with a pinion 35 in mesh with the driving gear 33, so that rotary motion is imparted individually to the rolls 3 and 4 from the pinion 33, to the roll 3 through the pinion35, shaft 17, and beveled gears 15 and 16, and to the r0114 through the pinion 32, sleeve 29 and beveled gears 27 and 28. h

The housing in which the pinion 33 .and shaft 34 are journaled is rigidly attached to the track 19 by bolts 36,and is provided with a yoke 37 in which is journaled an adjusting bolt 38 provided with a screw threaded section 39, which enters a screw threaded nut 40 attached to the housing 2. The bolt 38 is held from longitudinal movement in the yoke 37, and is provided with a polygonal enlargement 41 to receive a wrench, by which the bolt may be turned in order to adjust the position of the housing 2 on the track 19.

By loosening the bolts 20 and 26 both of A Tmm llberrele .lt 3 and ing pairs of rolls, and the position bf the ustment of said houslngs.

roll 3 relatively to the roll 4 may be determined sgiby the? adj usting screw: loosening the clampingbolts12and 13,.the roll 3, together with its bearings 7 and 8 and its attached pinion 15, may be lifted-ver- 'tic'ally free from the hou's ing1, but,

when-in operative position, the vertical pasition of'the roll 3 and pinion15 will be determined by the shoulder 14'. ['Similarly, the

roll 4 and its connected bearings and'pinion 27"may be removed from the housing 2by loosening the clamping bolts 21 and 22, and the vertical position of the roll 4 is determined in like manner as the roll? by a shoulder like the shoulder 14 shown in Fig.2. i i

As the bearings of the pinions 16 and 28 travel withthe housings 1 and 2, as the latter areadjusted, the beveled driving pinions of both rolls are always maintained in mesh,

any desired adjustment of the housings being provided for by the length of the teethrolls 3 and 4 as having vertical axes and, in

- and overlapping the raised flanges 43 of the housings 1 and 2, in order to prevent the admission of water from the rolls to the pinions. I likewise protect the bearings of the pinions 16 and 28 by means of hinged covers 44. The lower portions of the housings 1 and 2 are also provided with drip channels 45, to allow any water to escape which may lodge between the flanges 43 and the bearings 18 and 30. j

The. rolls are provided with circular plates 46, attached by bolts 47 to the upper ends of the roll gudgeons, said plates 46 overlapping and being in contact with the upper bearings, causing the rolls to be suspended.from the upper bearings, which are in turn supported upon the shoulders 14.
